About this tool
Organize routines, track doses, and receive real-time medicine reminders.
The Medicine Schedule Builder converts a prescription frequency into a dated dose timetable: pick OD, BD, TDS, QDS, HS, PRN or a strict q4h/q6h/q8h/q12h interval and it lays out every dose time across the whole course, with the total dose count and how many tablets or millilitres to keep in stock. The abbreviations are the standard Latin ones on Indian and UK prescriptions — TDS is ter die sumendum, three times a day — and the tool keeps the important distinction between three times a day, spread over waking hours, and every eight hours, which runs round the clock. It is an organiser for people managing a course or a parent's repeat prescription, not medical advice.
Open Medicine Schedule Builder on AltFTool — it loads instantly in your browser.
Enter 'Medicine name', 'Dose per intake' and 'Tablets / ml per dose', then set the 'Start date' and 'Course length (days)'.
Choose 'How often' — Once a day (OD / QD) through Four times a day (QDS / QID), At bedtime (HS), Only when needed (PRN) or Every 4/6/8/12 hours — plus 'First dose of the day' and 'Food instruction'.
Read 'Doses in the whole course' with 'Times each day' and 'Units to have in stock', scan the 'Every dose' table, then press 'Copy result'.
OD, BD, TDS, QDS, HS, PRN and hourly intervals, each with its usual clinical spacing.
Total doses multiplied by units per dose tells you exactly how much to have in stock.
Names, doses and dates stay in the browser; nothing is sent anywhere.
Ter die sumendum — three times a day. It is usually spread across waking hours, around 08:00, 14:00 and 20:00, unlike 'every 8 hours' (q8h), which is a strict interval that includes a night dose. BD is twice a day, QDS four times, OD once and HS at bedtime.
No, and the difference matters for antibiotics. Three times a day spaces doses over the waking day, so gaps are roughly 6-6-12 hours; every 8 hours keeps a constant gap and will require a dose during the night. If your label says q8h, set the interval option rather than TDS.
Doses per day × days × tablets per dose. A TDS course for 5 days at one tablet a dose is 3 × 5 × 1 = 15 tablets; the tool prints that figure so you can check a strip has enough before you start.
No. It only arranges the timing you enter and does no interaction, dose-limit or contraindication checking of any kind. Follow the label on your own prescription, and ask a pharmacist or doctor if it disagrees with anything shown here.
